Following a record year for profit in 2013, Delta Air Lines saw its earnings shoot up in Q1 2014. Net income was $213m, compared with $7m in the year-ago period, and the airline believes it is on track to achieve a whopping 14-16 per cent operating margin in the current quarter. Fuller aircraft will help achieve this, and Delta pushed its load factor up to 82.7 per cent in the last quarter – 1.5 points more than in Q1 2013. Recent results were also helped by lower fuel prices, although these contributed to a $41m loss at Delta’s Trainer oil refinery. Production at the facility suffered due to upgrade work during the quarter, although Delta expects the modifications to improve profitability going forward.
